Version v0.48.1

Changed

• 3243: Migrating from standard Debian slim base Docker images to GCR Distroless images.
• 3255: Adds client & server support for the existing protobuf HTTP-based remote RPC block accessor.
• 3259: Bump wasmtime to 0.43.1

Fixed

• 3258: Fix backward-compatiblity of GraphQL queries for pre-0.48.0 versions
• 3261: Fix PoA leader deadlock after reconciliation import where ensure_synced() blocked forever because execute_and_commit marked reconciliation blocks as Source::Network, causing the SyncTask to transition to NotSynced.
• 3264: Rollback stale preconfirmations in the mempool when the canonical block at that height omits the preconfirmed transactions, restoring spent inputs and removing dependent transactions.
• 3269: Fix PoA reconciliation deadlock when the same block exists on all Redis nodes but with different epochs. unreconciled_blocks now groups votes by block_id only (tracking max epoch as tiebreaker), so identical blocks written during re-promotion storms count toward quorum.
• 3272: Improve performance of redis block publish by making more parallel and optimizing the lua code
• 3278: Fix mainnet block-production hang when a single ElastiCache leader-lock node enters a half-alive state. Bumps redis to 1.2 (the older 0.27 client did not apply the connect timeout to the post-connect handshake pipeline) and short-circuits publish_block_on_all_nodes on quorum so a stuck per-node thread can no longer wedge the publish path.
• 3281: Add forward-compatibility for old clients and new fuel-core
